APPARATUS FOR DYEING.

SPECIFICATION forming` part of Letters Patent NoY 782,008, dated February '7, 1905l Application led November 30,1903. Serial No. 183,282.

To /r// 'l1-7mm n? may concern:

Be it known that I, LoN DTR, dyer, a citizen of the French Republic, residing' at Bheims, Department of Marne, France, have invented certain new and useful Improvements in Connection with Apparatus for Dyeing' under Pressure, of which the following' is a specification.

lThis invention has for its object to provide in apparatus for dyeing' under pressure means whereby the introduction of the dyes or mordants into the apparatus can be effected while the apparatus is at work and while the pressures remain in the Various vessels composing the apparatus.

The most recent design of apparatus for dyeing under pressure is illustrated in the accompanying drawing and comprises two vessels A and B, containing' the dyestufi', and another vessel or other vessels, C C, containing the articles or material to be dyed. Uompressed air or any other suitable fiuid pressure is admitted alternately to each of the two vessels A and B containing' the dye, so as to force the dye from, say, the vessel A into the vessel containing' the articles or materials to be d yed,and from the said vessels into the second vessel.I say the vessel B. Then by means of a cock the pressure is disconnected from the vessel A and admitted to the vessel B, thereby forcing' the dye from the vessel B into the vessel C and therefrom back into the vessel A. 'lhe cock for reversing'the direction of the pressure is a four-way cock lt,which is worked automatically, so as to cause the air or other pressure to act alternately in each of the two vessels A B, the other vessel communicating' with the atmosphere.

The device constituting' this invention consists in the addition to the apparatus just described of a closed vessel D, into which the dyestutl to replenish the vessels A B is introduced by means of a funnel E, provided with a cock Q. Two pipes connect the vessel D with the top of the vessels A B, the said pipes passing th rough lierineticall y-tig'ht joints provided in the cover of the vessel D and extending; nearly to the bottom thereof. These pipes are provided with cocks 3 and JL, respectively, permitting of opening or closing it at will.

Another pipe, also provided with acock l, connects the vessels l) with one of the vessels A, B, (l, or U. ln the accompanying' drawing this pi'pe is shown connecting; directly to the vessel C.

In order to introduce into the vessels A and B a quantity of new dyestutl, the cocks 2, 3, and 4L are closed and the cock .1 is opened, so as to allow' a certain quantity of the dyestuti` to flow into the vessel l) from the vessel (l. The cock 1 is then closed and the cock Q opened and the dyestulf or mordant introduced through the lfunnel 1C into the vessel l). The cock Q is then closed and the cocks 3 and A are-opened, then compressed air coming from the vessel A or B, in which pressure is then existing', say the vessel A, forces the liquid contained in the vessel D toward the vessel B,whence it takes part again in the circulation through the apparatus and carries with it the whole oi; part of the dyestufl' or mordant from the vessel D. The series of the successive pulsations of the apparatus sup-- plies ina perceptibly equal manner to the vessel A and tothe vessel B the. dyestutf contained in the vessel D until the vessel D is entirely exhausted. The cocks 3 and 4 are then closed to isolate the vessel D, the apparatus being then in its normal working' condition.

()ne of the two tubes running' from the vessels A and B need not necessarily dip into the liquid contained inthe vessel I). ln this case the introduction of the additional dyestutt' would take place only on one side of the apparatus. 'lhe apparatus could likewise be worked by deriving' the pressure from any source of elastic tluid, such as a steam-generator, a compressed air org'as reservoir, or the like. rlhe vessel l) may be provided with a glass gage, so that the working' of the apparatus can be readily seen.

Having now particularly described and ascertained the nature of this' invention and in what manner the same is to be pm'formed` l declare that what I claim isln a dyeing' apparatus, a plurality of closed dye-tanks, a plurality of article-receiving' tanks, pipes leading from the lower portions of the dye-tanks and having branches con- IO involvinga four-way oook, and a valved funneoted at separated points with the lower por- 1 nel Connected with the top of the dye-resertions of the respective article-receiving tanks, Voir. a closed dye-reservoir communicating with a In testimony whereof I have hereunto set dye-tank, pipes extending through the top of my, hand in presence of two Subscribing wit- 5 the dye-reservoir and having their lower ends nesses.
